Artefacts of PET/CT images

Positron emission tomography (PET) is a non-invasive imaging modality, which is clinically widely used both for diagnosis and accessing therapy response in oncology, cardiology and neurology. Fusing PET and CT images in...

Tomotherapy as a tool in image-guided radiation therapy (IGRT): theoretical and technological aspects

Helical tomotherapy (HT) is a novel treatment approach that combines Intensity-Modulate Radiation Therapy (IMRT) delivery with in-built image guidance using megavoltage (MV) CT scanning. The technique utilises a 6 MV lin...

Image-guided stereotactic body radiation therapy (SBRT): an emerging treatment paradigm with a new promise in radiation oncology

Evaluation of radiation dose and image quality following changes to tube potential (kVp) in conventional paediatric chest radiography

Purpose: A study of radiation dose and image quality following changes to the tube potential (kVp) in paediatric chest radiography. Materials and Method: A total of 109 patients ranging from 1 month to 15 years were inc...

The impact of lesion vascularisation on tumours detection by electrical impedance scanning at 200 Hz

Objective: Cancer cells exhibit altered local dielectric properties compared to normal cells. These properties are measurable as a difference in electrical conductance using electrical impedance scanning (EIS). EIS is at...
